Just to thinking, cause here is an example. One of the topics that we're going to cover is about networks and network effects. So we all are familiar with these type of industries are connected through networks, for example, the telephone, the trains, the roadways. But now, with the digitalization, we have seen the arrival of new type of companies, for example, websites, apps, platforms. And in this way, this type of digital businesses, they have created something that is called a network effect. Here we have the example of four different companies that we're going to cover through our course Facebook, Airbnb, medium and WhatsApp. And we are going to see how they have created this network effect. And that's going to effect is the state when the more users that you get, the more value they get because they are nurturing each other. For example, this is very clear with their reviews. Now, if I know a place where somebody has tested before and then I want to rent it, I would be sure, certain that they have a good review, that they have a good mark. Is the same also for the owners? If I know that these clients, they behave well, then I would be willing more easily and trusting all these reviews to give them my place for rental. So in all these four cases, we are going to cover four things. The product value that they they offer, the growth tactic that they have, use, how they have, engage users to keep using these different platforms. And finally, the the massive point that they have reached for. No. Perfect. So stay tuned. And I see you in IMIM in our city thinking course.
